Initial queries related to relocation to Brighton, UK from India

Hi friends

I am considering an opportunity to take up an assignment from my current company (Indian IT services company) in Brighton, UK.

I did some basic internet search and got some info but have few initial questions in mind. Your answers will really help me:

1) Considering I get the minimum salary of 41.5k GBP, what will be my in hand salary per month / year considering various deductions, taxes etc. Don't know much about UK taxation.

2) What is the expected rent amount for a single person if I wish to stay in a small but furnished studio or 1 room apartment?

3) How are the Indian grocery stores and vegetarian food options in Brighton?

4) How is the public transportation in Brighton? Can one manage without a car?

5) Overall, what is the kind of monthly expenses one can expect considering the lifestyle is neither lavish nor too frugal?

6) How easy is it to find flat sharing options with other Indians?

7) Any good Indian tiffin / dabba services? (I was in sydney for a year and had plenty of options there)

8) Overall how big is the Indian population / community in Brighton?

9) My work location/client will likely be AMEX. How far is their office (IT) from the city center?

10) Anything else you feel significant, please feel to share.

Thanks.
